[Amn Orakzai]

Greetings!!
Guys i was having low data on my samsung galaxy grand, so i go to setting and uder storage area i deleted the miscellaneous files. I was having important files (photos, videos) hidden by NQ Vault, so when i opened it up nothing was there and all of them was lost. So anybody help in getting them back, no matter its software or i have to root it. plz help me in regarding recovering of my data.

Sorry to say it but this will almost certainly be impossible.

For one thing, the Android OS makes very dynamic use of memory and no sooner you clear some up by deleting files, the OS finds something else to put there.

Secondly, if your phone is not already "unlocked" then the mere process of unlocking the boot loader prior to rooting it will totally wipe the device's memory.
